Billye was Gilmer's consort from the time he'd been an ambitious young lieutenant right through his sack of Trantor and self-proclamation as Emperor of the Galaxy. On most planets she would be considered beautiful, but on Trantor the population was so huge that Gilmer knew he could find a lovelier woman still. He considered replacing her, reasoning that an emperor should have the most beautiful woman available as his consort.

After Gilmer returned from ceasefire negotiations with Dean Yokim Sarns of the Galactic University, Billye berated him for being too generous in his terms with the scholar. Gilmer, still deeply rattled from his tour of the Imperial Library, had no patience for such criticism and roared at Billye, demanding her silence. Though any of Gilmer's half-pirate mercenaries would have been terrified by the display of fury, Billye continued to goad Gilmer. As punishment, Gilmer had Billye physically thrown out of the palace and replaced with a Trantorian woman who was not only more beautiful but less critical.
